🚨 A Tooth Infection Can Spread Beyond the Mouth and Become Life-Threatening
A tooth infection is more than a painful tooth. If left untreated, bacteria can spread beyond the tooth into nearby tissues and, in severe cases, enter the bloodstream, triggering a dangerous body-wide inflammatory response.
Most tooth infections begin when bacteria enter the pulp through deep decay, a cracked tooth, trauma, or a leaking restoration. As the bacteria multiply, they can form a dental abscess—a pocket of pus at the root of the tooth or in the surrounding gum.
Warning signs that require prompt dental evaluation include: • Severe, persistent, throbbing tooth pain • Swelling of the face, jaw, or gums • Fever • Pain while chewing or biting • Difficulty swallowing or breathing
Although uncommon, a severe untreated dental infection can spread into deeper tissues. In rare cases, bacteria may enter the bloodstream and contribute to sepsis—a life-threatening medical emergency that requires immediate treatment.
Early dental care, including drainage of the infection, root canal treatment, or tooth extraction when necessary, can stop the infection from spreading and help prevent serious complications.
